25 massive metro systems that run the world
The sprawling metro systems of the world enable residents and travelers alike to reach the furthest corners of a city. From Chicago's famed elevated "L" to Hong Kong's ultra-modern Massive Transit Railway, these transportation networks blend convenience and comprehensiveness with the permanence and cost of truly ambitious urban projects.
To help guide your next global adventure, we've identified the 25 largest metro systems in the world by overall route length, using data published in news releases, government reports, and the metro-operating companies themselves. Our analysis focuses on heavy rail systems—dedicated, mass-transit rail systems designed to move residents through a city with speed—as opposed to light rails and commuter trains that typically serve the outer limits of a metro area.
Together, these transportation networks account for over four billion miles of possible travel. For each metro system on our list, you'll find an image that encapsulates the sprawling city serviced, as well as a handy route map for your travels.
